Hi guys does anyone know how small I can go on the rear rims on an XFR and clear the brakes ?

I'm thinking about getting a pair of wider rims and drag radials for the track but 20s are so expensive, I'm hoping I can go 18 or 19 inch.

 

You should be able to go 19" but I do not think 18" will fit, but only on the back.


The rear rotors are 376mm (14.8") in diameter. The only thing that might help is the calipers are much smaller in mass than the front calipers.


Good luck
